The possibility to save design rule to save/load design rule to file is really handy and as far as I could tell this seems very good to check for manufacturing limitations.

For hight voltage extra space is usually need in form of clearance and creapage distances between some nets. It is also common nets with higher current need rule for mininum width. Radio frequency often have requirement for both "clearance" and net width. These are however not manufacturing limitations.
